Abstract

Objective: To explore the antiarthritic potential of a novel synthetic cannabinoid acid, Hebrew University–320 (HU‐320), in the DBA/1 mouse model of arthritis, and to investigate in vitro antiinflammatory and immunosuppressive effects of HU‐320 on macrophages and lymphocytes. Methods: DBA/1 mice were immunized with bovine type II collagen (CII) to induce arthritis and then injected intraperitoneally daily with HU‐320. The effects of treatment on arthritic changes in hind feet were assessed clinically and histologically, and draining lymph node responses to CII were assayed. Murine splenic and human blood lymphocytes were cultured to study the effect of HU‐320 on polyclonal mitogenic stimulation. Macrophage cultures were set up to evaluate in vitro effects of HU‐320 on production of tumor necrosis factor α (TNFα) and reactive oxygen intermediates (ROIs). The effect of HU‐320 administration on lipopolysaccharide‐induced serum TNF levels was assayed using C57BL/6 mice. Bioactive TNF production was measured using BALB/c clone 7 target cells. Evaluation of HU‐320 psychoactivity was performed using established laboratory tests on Sabra mice. Results: Systemic daily administration of 1 and 2 mg/kg HU‐320 ameliorated established CII‐induced arthritis. Hind foot joints of treated mice were protected from pathologic damage. CII‐specific and polyclonal responses of murine and human lymphocytes were down‐modulated. HU‐320 inhibited production of TNF from mouse macrophages and of ROIs from RAW 264.7 cells and suppressed the rise in serum TNF level following endotoxin challenge. HU‐320 administration yielded no adverse psychotropic effects in mice. Conclusion: Our studies show that the novel synthetic cannabinoid acid HU‐320 has strong antiinflammatory and immunosuppressive properties while demonstrating no psychoactive effects. The profound suppressive effects on cellular immune responses and on the production of proinflammatory mediators all indicate its usefulness as a novel nonpsychoactive, synthetic antiinflammatory product.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
